Bash Version: 3.2
Patch Level: 33
Release Status: release

Description:
        When I execute edit-and-execute-command realdline command by typing 
C-xC-e,
        it seems that bash always launch emacs whatever the setting of
FCEDIT env variable.
        However man bash say the opposite.

Good catch.  The command executed is actually

fc -e "${VISUAL:-${EDITOR:-emacs}}"

It's the same command for vi and emacs editing modes, though the default
for vi editing mode is `vi' instead of `emacs'.  The documentation needs
to be updated, and has for a while, since it's been this way since at
least bash-2.05.  Seven years is a long time for this to go unnoticed.
